BACKGROUND

The present invention relates generally to orthopedic positioning devices and more particularly to devices and methods for supporting an arm before, during or after a surgical, rehabilitative or imaging procedure.

Surgical procedures on the extremities of humans occur with great frequency, and particularly surgeries on the arm, elbow, and hand. Injuries to a person's arm, elbow and hand come frequently from falls, reaching to catch one's self, slipping or landing on an elbow causing a shattering or dislocation of the bone structure within the elbow, and attempting to brace oneself in response to a fall resulting in fractured bones in the humerus, elbow, forearm, and/or hand.

During the course of procedures to repair the broken bones or other features in the arm, historically, the patient's arm has been placed on a pillow or some other support structure resting on the patient's waist or chest, or a foam pad can be used to support the arm. This procedure fails to properly secure and maintain in a fixed position the extremity on which the procedure is being conducted. There have been numerous attempts to address this problem, including those described and illustrated in U.S. Pat. Nos. 473,200; 5,785,057; 7,017,215; 7,143,458; 7,441,293 and U.S. Publication No. 2008/0301878. The prior devices that are available in the industry, including those described in the aforesaid patents are an improvement over the simple use of a pillow resting on the patient's chest, but remain inadequate. Specifically, conventional products fail to provide good exposure to the extremity, particularly to the patient's elbow, and make it difficult for the surgeon and assistants to have easy, unfettered access to the patient's elbow to properly complete the surgical, rehabilitative or imaging procedure. Additionally, conventional support devices do not allow vertical or longitudinal adjustment of a stabilizer bar and other modular attachments for the support device. Other support devices also generally do not allow interchangeability of different modular components for supporting different parts of the arm in different positions. Thus, there is a continuing need in the art for improvements in devices and methods for supporting an arm for such purposes.

DETAILED DESCRIPTION

Referring now to the drawings, FIG. 1 illustrates a perspective view of an embodiment of an arm stabilizer generally designated by the numeral 10. In the drawings, not all reference numbers are included in each drawing, for the sake of clarity. In addition, positional terms such as “upper,” “lower,” “side,” “top,” “bottom,” “vertical,” “horizontal” etc. refer to the apparatus when in the orientation shown in the drawings or similar orientations. A person of skill in the art will recognize that the apparatus can assume different orientations when in use.

Referring further to FIG. 1, an embodiment of a rail clamp 100 in accordance with the present disclosure is generally illustrated. Rail clamp 100 is generally configured for attachment to a side rail or other similar structure on a table such as an operating table or a surgical table. Similar types of rails may be found on other structures for supporting or transporting patients. Rails of this nature include a universal mounting configuration in some applications to allow for interchangeability of attachments. Rail clamp 100 includes a clamp base 112 having a clamp jaw 110, or pawl, that is hinged about a pawl axis 124 on the clamp base 112. A mounting recess 106 is defined between clamp base 112 and clamp jaw 110 shaped to receive the rail on which rail clamp 100 is to be mounted. A rail clamp fastener 104 allows clamp jaw 110 to be tightened against the rail. A handle is positioned on the rail clamp fastener 104 to allow for manual adjustment of the force applied to clamp jaw 110.

Rail clamp 100 may be positioned along the longitudinal length of a rail 24 by simply loosening the rail clamp fastener 104, repositioning the rail clamp 100, and then re-tightening the rail clamp fastener 104. This allows the rail clamp 100 to be moved relative to a patient's location on the table 25.

Rail clamp 100 is further configured to receive multiple modular attachments for use in supporting a patient's arm or other extremity during use. Rail clamp 100 includes a clamp body 120 protruding upwardly from the clamp base 112. Clamp body 120 includes a longitudinal section that is configured to extend generally upwardly away from the rail during use. A longitudinal socket 128 is defined in the rail clamp 100 in some embodiments. Socket 128 is shaped to receive a portion of a modular attachment in the socket.

As seen in FIG. 2, one type of modular attachment for installation on rail clamp 100 includes an arm stabilizer, or support arm 10. Support arm 10 includes a stabilizer bar 12 and a base 14. The stabilizer bar 12 is pivotally attached to the base 14 in some embodiments. In alternative embodiments, stabilizer bar 12 and base 14 include a rigid configuration on support arm 10. Base 14 includes a longitudinal shaft in some embodiments. The shaft on base 14 is shaped to be inserted longitudinally in socket 128 on rail clamp 100 in some embodiments. The shaft may form a rod having a round, oval or polygonal cross-sectional profile in various embodiments. The shaft of base 14 is dimensioned to fit in socket 128 on rail clamp 100. The shaft may be loaded into socket 128 in a generally vertical orientation after rail clamp 100 is secured to a rail on a table. Alternatively, the shaft of base 14 may be installed into the socket 128 on rail clamp 100 prior to attachment of rail clamp 100 to the rail on the operating table.

Base 14 is secured in place on rail clamp 100 using a socket fastener 108 in some embodiments. Socket fastener 108 includes a threaded fastener inserted in a transverse threaded bore in the clamp body 120 on rail clamp 100. Socket fastener 108 may be tightened against a portion of base 14 housed in socket 128 to secure the base 14 in place, as seen in FIG. 3. Base 14 is longitudinally adjustable relative to rail clamp 100 in some embodiments, as seen in FIG. 4. Socket fastener 108 may be loosened, and base 14 may be slid up or down to accommodate patients of different sizes. When a proper position is reached, socket fastener 108 is re-tightened to hold the base 14 in place. The ability to load and unload base 14 into or away from rail clamp 100 in a longitudinal orientation provides an advantage over other loading configurations in some applications because a longitudinal configuration allows displacement of the base 14 substantially parallel to a patient's humeral region without causing the stabilizer bar 12 to laterally interfere with the patient's arm.

Referring further to FIGS. 1-4, rail clamp 100 also includes a clamp groove 102 in some embodiments. Clamp groove 102 generally includes a recess defined on the clamp body 120 forming a channel for attachment of one or more modular components. Clamp groove 102 includes a blind recess in some configurations forming a slight channel for receiving a corresponding structure. The clamp groove 102 allows a modular attachment to be slid along the length of the groove for positioning of the attachment. Alternatively, clamp groove 102 provides a clearance groove that is open to the socket 128 such that the portion of base 14 extending into socket 128 is visible through the clearance in the clamp groove 102. In such configurations, a user may be able to visually inspect the location of base 14 in socket 128. This allows a user to ensure the base is sufficiently installed a proper depth into socket 128 to provide adequate support. If base 14 does not extend far enough into socket 128, support arm 10 may inadvertently become loosened from the rail clamp 100 and allow undesirable motion during use. By providing a clamp groove 102 having a clearance section, it is possible to visually verify the base 14 is located at a proper position in the socket 128. Accordingly, in some embodiments, base 14 has indicia at a predetermined location such that a user may visually inspect the location of base 14 relative to socket 128.

Clamp body 120 provides a mounting location for one or more modular attachments. As seen in FIGS. 2-4 and FIGS. 8-9, a humeral support attachment 50 is mounted on rail clamp 100 in some embodiments. More specifically, humeral support attachment 50 includes humeral support mount 56 shaped to be installed on rail clamp 100. Humeral support mount 56 may be slid onto clamp body 120 as shown in FIGS. 8-9. A humeral mount fastener 54 is positioned on humeral support mount 56 to secure humeral support attachment 50 at a desired location on rail clamp 100. Humeral mount fastener 54 includes a threaded fastener extending through a corresponding threaded hole in humeral support mount 56. The humeral support mount 56 may be slid up or down along the longitudinal length of clamp body 120 on rail clamp 100 and secured at a desired location using humeral mount fastener 54.

A humeral support arm 52 protrudes from humeral support mount 56 in some embodiments. Humeral support arm 52 extends generally transverse to the longitudinal orientation of rail clamp 100 in some applications. Humeral support arm 52 includes a slide 58 disposed through a humeral mount opening 48 in humeral support mount 56 in some embodiments. Slide 58 is moveable through humeral mount opening 48 to allow the humeral support arm 52 to be selectively repositioned relative to the rail clamp 100. As such, a user may modify the distance the humeral support arm 52 extends from rail clamp 100. This may be advantageous when configuring the device to support patients of different sizes.

As seen in FIG. 4, in some embodiments, humeral support arm includes a first humeral support arm section 52 a and a second humeral support arm section 52 b separated at a humeral support arm bend 53. The first and second humeral support arm sections are angled at a generally obtuse angle. In some embodiments, this angle is between about 180 degrees and about 140 degrees. The slight angle between these sections provides improved support of the humeral section of the patient's arm during use.

In some embodiments, humeral mount fastener 54 secures the humeral support arm 52 in place by applying force against the slide region 58 of humeral support arm 52 and also secures the humeral support mount 56 in place relative to the rail clamp 100. As seen in FIG. 9, tightening the humeral mount fastener 54 applies force against the slide region 58 on the humeral support arm 52. The applied force presses the other side of the slide region 58 against the surface of the clamp body 120 on the rail clamp 100, thereby securing both the humeral support arm 52 and the humeral support mount 56 in place relative to the rail clamp 100. In some embodiments, the present invention provides a humeral support attachment including a humeral support arm that is moveable in two axes relative to the rail clamp. Specifically, the humeral support arm is vertically moveable along the longitudinal direction of the clamp body and is also moveable transverse to the clamp body in the longitudinal direction of the humeral support arm. This provides an advantage over conventional humeral support devices that may be fixed in place relative to the rail clamp or otherwise limited to adjustment along only one axis.

Referring further to FIGS. 2-4, in further embodiments one or more modular attachments may be secured to the stabilizer bar 12 on support arm 10 to form arm positioner device 200. Stabilizer bar 12 includes a longitudinal bar having a proximal bar end 18 located near base 14 and a distal bar end 20 extending away from base 14. One or more modular attachments may be secured to the stabilizer bar 12 between the proximal and distal bar ends. For example, a wrist support attachment 70 is secured to the stabilizer bar 12 on support arm 10 in some embodiments. Wrist support attachment 70 provides a structure for supporting a wrist, forearm or hand region on a patient during use. Wrist support attachment includes a wrist support mount 76 and a wrist support bar 72 protruding from the wrist support mount 76 in a direction away from the stabilizer bar 12. Wrist support mount 76 engages the stabilizer bar 12 and includes a wrist support fastener 74 for securing the wrist support attachment 70 to the stabilizer bar 12 in some embodiments. Wrist support fastener 74 includes a threaded fastener in some embodiments. Wrist support fastener 74 applies a force against the side of the stabilizer bar 12 to secure the wrist support attachment 70 in place. Wrist support attachment 70 may be repositioned along the length of the stabilizer bar 12 by loosening the wrist support fastener 74, repositioning the wrist support mount 76 to a desired location along the length of stabilizer bar 12, and then retightening wrist support fastener 74. The ability to reposition the wrist support attachment 70 relative to the stabilizer bar 12 provides an advantage over other supports that are fixed in place.

As seen in FIG. 4, in some embodiments, wrist support bar 72 includes an angled end to further support a patient's wrist, hand or forearm and to keep the patient's extremity from inadvertently sliding off the end of the wrist support bar 72. Additionally, a mounting groove may be defined in the stabilizer bar 12 along the length of the stabilizer bar 12. One or more structures on the wrist support mount 76 extend at least partially into the mounting groove on the stabilizer bar 12. As such, the mounting groove in the stabilizer bar operates as a track along which the wrist support mount 76, or any other modular attachment, may slide during adjustment of the attachment.

Referring further to FIGS. 3-4, another type of attachment known as a reducer attachment 30 may be positioned on the stabilizer bar 12. Reducer attachment 30 provides structural support for a patient's humeral region, elbow, or forearm during use. In some applications, a reducer support arm 32 extends from a reducer mount 34 on the reducer attachment. Reducer support arm 32 may be located near a patient's elbow joint, as seen in FIG. 10, when a patient is lying in a supine position on an operating table. The reducer support arm 32 supports an underside portion of a patient's arm and provides a reaction structure against which a physician may apply force during an operation on the patient's arm or elbow.

Referring further to FIG. 4, reducer attachment 30 includes a generally L-shaped reducer support arm 32 in some embodiments including a first reducer support arm section 32 a and a second reducer support arm section 32 b oriented at an angle relative to the first reducer support arm section 32 a. These two sections join at a reducer attachment bend 33 and form a substantially right angle in some embodiments. The second reducer support arm section 32 b extends away from the stabilizer bar 12 and provides support to the user's arm.

The reducer attachment 30 includes a reducer mount 34 that engages the stabilizer bar 12. A reducer fastener 36 on the reducer mount 34 provides a force against the stabilizer bar 12 to secure the reducer attachment 30 in position. Reducer fastener 36 includes any suitable fastener such as a threaded fastener for applying force against the stabilizer bar 12. A user may adjust the position of the reducer attachment 30 on the stabilizer bar 12 by loosening the reducer fastener 36, repositioning the reducer attachment at a desired location along the length of the stabilizer bar 12, and then retightening the reducer fastener 36. In some embodiments, the reducer fastener 36 engages a mounting groove on the stabilizer bar 12, where the mounting groove operates as a track along which the reducer mount 34 may be slid for positioning the reducer attachment 30.

The reducer attachment 30 may be used on the arm positioner device 200 as the only modular attachment. For example, in some embodiments, the arm positioner device 200 includes only the rail clamp 100, the support arm 10 and the reducer attachment 30. In other embodiments, arm positioner device 200 includes only the rail clamp 100, and humeral support attachment 50, as seen in FIGS. 8-9. In further embodiments, the arm positioner device 200 includes only the rail clamp 100, support arm 10, humeral support attachment 50, and wrist support attachment 70. In additional embodiments, the arm positioner device 200 includes only the rail clamp 100, support arm 10, and wrist support attachment 70. In further embodiments, the arm positioner device 200 includes only the rail clamp 100, support arm 10, wrist support attachment 70, and reducer attachment 30. In yet other embodiments, the arm positioner device 200 includes the rail clamp 100, support arm 10, wrist support attachment 70, humeral support attachment 50 and reducer attachment 30.

Referring further to FIGS. 5-7B, in some embodiments the stabilizer bar 12 is angularly moveable relative to the base 14. As such, stabilizer bar 12 is also angularly moveable relative to rail clamp 100 when base 14 is installed on the rail clamp. As seen in FIG. 5, stabilizer bar 12 may be oriented relative to rail clamp 100 at a first angle 22 a. The first angle may be approximately ninety degrees in some embodiments. A first angle stop 78, shown in FIG. 7A, on support arm 10 provides an angular stop for stabilizer bar 12. Stabilizer bar 12 is attached to base 14 at a base hinge 16 in some embodiments. Stabilizer bar 12 may be angularly rotated back as shown in FIG. 6 to a second angle greater than ninety degrees.

In some embodiments, support arm 10 includes an angular lock to secure stabilizer bar 12 at a desired angle. For example, as seen in FIGS. 7A and 7B, a base head 42 is positioned on base 14 in some embodiments. Base head 42 includes a pivot opening 44. A locking pin 26 attached to stabilizer bar 12 extends transversely through and is rotatable in pivot opening 44. A locking slot 46 adjoins and is open to pivot opening 44. Locking pin 26 includes a substantially flat dimension shaped to be received in locking slot 46. Locking pin 26 may slide locking slot 46, as seen in FIG. 7B, when stabilizer arm 12 is positioned at a corresponding angular position. In some applications, the angular lock is configured to selectively lock stabilizer bar 12 in a substantially vertical configuration, as seen in FIG. 6. When a user desires to unlock the angular lock, the stabilizer bar 12 may simply be lifted up to disengage locking pin 26 from locking slot 46, thereby allowing free rotation of locking pin 26 in pivot opening 44.

In some applications, it is desirable to provide a back angular stop on support arm 10 such that stabilizer bar 12 does not rotate too far away from the patient during use. As such, a second angular stop 80 is positioned on base head 42 in some embodiments. Second angular stop allows support arm 10 to be rotated away from a patient when not in use.

Referring further to FIGS. 11-13, additional embodiments of the present invention provide a lateral positioner device that may be used to support a patient's arm in a face down or prone position or in a lateral position. An advantageous feature of the present invention is the ability to use the rail clamp 100 interchangeably with either an arm positioner device 200, as shown in FIGS. 2-6 and with a lateral positioner device 300, as shown in FIGS. 11-13. Lateral positioner device 300 includes a rail clamp 100 as described above. A lateral brace 60 is securable to the rail clamp 100 to provide support to a patient's arm in a prone position, as seen in FIG. 13, or in a lateral position. Lateral brace 60 includes a longitudinal post 62 shaped to be inserted longitudinally in socket 128 on rail clamp 100. Lateral support arms 64 extend from post 62 at a T-shaped junction in some embodiments. First and second lateral support arms 64 a, 64 b intersect at post 62 and generally extend away from post 62 at an upward angle, as seen in FIG. 12. A brace recess 68 is defined between first and second lateral support arms 64 a, 64 b. A patient's arm is located in the brace recess 68 during an operation. Lateral brace 60 may support a patient's humeral region along the bicep or may engage the patient at or near the elbow joint.

In some embodiments, lateral brace 60 has an adjustable height such that the brace may be repositioned relative to rail clamp 100. For example, as seen in FIG. 12, post 62 is longitudinally adjustable in socket 128 on rail clamp 100. Socket fastener 108 may be tightened against post 62 to secure lateral brace 60 at a desired height. To adjust the height of lateral brace 60, a user may loosen socket fastener 108, reposition post 62, and then retighten socket fastener 108. In some embodiments, post 62 includes a substantially flat surface 66 to provide enhanced application of force from socket fastener 108. Additionally, in some embodiments, flat surface 66 prevents inadvertent rotation of post 62 when engaged by socket fastener 108.

Referring further to FIGS. 14-16, various pad attachments may be positioned on each modular attachment to provide a padded interface between the attachment and a user's arm. For example, as seen in FIG. 14, humeral support attachment 50 includes a humeral support arm 52. A humeral support pad 51 includes an elongated pad having a hollow interior aperture shaped to receive the humeral support arm 52. In some embodiments, humeral support pad 51 includes a generally cylindrical hollow tubular shape. As such, the humeral support pad 51 may be slid directly onto the humeral support arm 52, as seen in FIG. 15. Humeral support pad 51 includes pad material such as but not limited to an open-cell or closed-cell foam material, foam rubber, polyethylene padding, latex padding, EVA padding, or any other suitable padding material. Humeral support pad 51 includes a disposable pad that may be discarded after use in some applications.

Referring further to FIG. 14, reducer attachment 30 includes a reducer support arm 32. A reducer support pad 31 includes an elongated pad having a hollow interior aperture shaped to receive the reducer support arm 32. In some embodiments, reducer support pad 31 includes a generally cylindrical hollow tubular shape. As such, the reducer support pad 31 may be slid directly onto the reducer support arm 32, as seen in FIG. 15. Reducer support pad 31 includes pad material such as but not limited to an open-cell or closed-cell foam material, foam rubber, polyethylene padding, latex padding, EVA padding, or any other suitable padding material. Reducer support pad 31 includes a disposable pad that may be discarded after use in some applications.

Referring further to FIG. 14, wrist support attachment 70 includes a wrist support arm 72. A wrist support pad 71 includes an elongated pad having a hollow interior aperture shaped to receive the wrist support arm 72. In some embodiments, wrist support pad 71 includes a generally cylindrical hollow tubular shape. As such, the wrist support pad 71 may be slid directly onto the wrist support arm 72, as seen in FIG. 15. Wrist support pad 71 includes pad material such as but not limited to an open-cell or closed-cell foam material, foam rubber, polyethylene padding, latex padding, EVA padding, or any other suitable padding material. Wrist support pad 51 includes a disposable pad that may be discarded after use in some applications.

Referring further to FIG. 12 and FIG. 16, lateral positioner device 300 may also include one or more pads on first and second lateral support arms 64 a, 64 b. For example, a first lateral support arm pad 61 a is positioned on first lateral support arm 64 a, and a second lateral support arm pad 61 b is positioned on second lateral support arm 64 b. Each lateral support arm pad 61 a, 61 b includes an elongated pad having a hollow interior aperture shaped to receive its corresponding lateral support arm. In some embodiments, each lateral support arm pad includes a generally cylindrical shape. Each lateral support arm pad may be slid directly onto its corresponding lateral support arm, as seen in FIG. 16. Each lateral support arm pad includes pad material such as but not limited to an open-cell or closed-cell foam material, foam rubber, polyethylene padding, latex padding, EVA padding, or any other suitable padding material. Each lateral support arm pad includes a disposable pad that may be discarded after use in some applications.

Referring further to FIGS. 17-19, a pad kit apparatus 400 is provided in some embodiments. Pad kit apparatus 400 includes a package including first, second and third pads 402 a, 402 b, 402 c housed within a sealed enclosure 404. Enclosure 404 provides a sealed, sterile package for first, second and third pads. A user may open enclosure 404 to access the pads. First and second straps 406, 408 are included in the package in some embodiments. Each strap includes a hook-and-loop fabric in some embodiments to provide a fastener for securing a portion of a patient's body to one of the first, second and third pads. Each strap is dimensioned to extend around a patient's arm, hand or wrist and also around one of the first, second and third pads in some embodiments.

In some embodiments, each of the first, second and third pads include substantially identical dimensions. As such, each pad is generally interchangeable and may be used as a humeral support pad 51, a reducer support pad 31, a wrist support pad 71, or a lateral support arm pad 61.
